The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
